Overview
- The eclipse is set for the night of Thursday, August 27 into the early hours of Friday, August 28, with the maximum near 1:13 a.m. ART for Buenos Aires and about 12:12 a.m. EDT on the U.S. East Coast.
- Astronomical agencies call it a very deep partial eclipse: published estimates range from roughly 93% to about 96% of the Moon entering Earth’s umbra, which will make the event appear almost total to most viewers.
- The reddish or copper tones that may appear come from sunlight filtered and refracted through Earth’s atmosphere before it reaches the Moon, a process described by planetary scientists and communicators.
- Viewing is safe with the naked eye and does not require protective filters; binoculars or small telescopes will add detail but are optional for enjoying the event.
- Public observing programs (Rosario, Planetario Galileo Galilei, Medellín) and live streams (NASA TV, observatory feeds) are available, though local weather — including a forecasted 40% chance of rain for Buenos Aires’s AMBA region tied to a Santa Rosa storm — could block the view.
